摘要： A wheel structure that makes braking easy and prevents sudden stops, and a pushcart having the wheel structure are provided. The wheel structure includes a rotor that is rotatable about an axle and is stopped from rotating by a brake member, a wheel that is coaxial with the rotor and is rotatable about the rotor, and a relative-rotation resisting member that is disposed between the rotor and wheel and produces resistance force resisting the relative rotation of the rotor and wheel.

摘要： A stroller capable of making braking easy and maintaining itself in a brake release state with a simple structure is provided. The stroller includes a body frame, wheels, a brake member located at a lower end of a leg section, and displaced between a braking position and a brake release position, an operating mechanism attached to the push rod, operatively associated with the brake member through a coupling member coupling the operating mechanism and the brake member, and being capable of being displaced between a first position corresponding to the braking position of the brake member and a second position corresponding to the brake release position of the brake member, a bias member biasing the brake member to move the brake member to the braking position, and a maintaining mechanism maintaining the operating mechanism in the second position corresponding to the brake release position.
